ROAD DIIGGER, AND SCRAPER.

SPECIFICATION forming part of Letters Patent No. 367,968, dated August9, 1887.

Applicationfiled August 18, 1886. Serial No. 211,199. (No model.)

To all whom it may concern/.-

Be it known that I, ALBERTO FINKS,Of New Berlin, in the county ofChenango and State of New York, have invented a new and Improved RoadDigger and Scraper, of which the following is a full, clear, and exactdefrom the ground, as desired.

The invention consists in the construction and combination of the parts,as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification,

.in which similar letters of reference indicate corresponding parts" inall the figures.

Figure 1 is a sideelevation of my combined digger and scraper. Fig. 2 isa transverse vertical section looking toward the rear, and Fig. 3 is aplan View with levers removed. Fig. 4 is a detail view of one of thediggerteeth.

The wagon adapted to be used in connection with my combined digger andgrader is formed with the front axle, A, shorter than the rear axle, A,and the said axles are connected by beams B B, which extend in a Vshape, suitably braced from front to rear, being supported above saidaxles by blocks 0 (J. Be-

- tween the block G of the front axle and the A, than the aforesaidsupport D. The pend ent supports D and D are stayed by front and axleitself a fifth-wheel, G, is attached, whereby the wagon is turned.

Supports D D are attached to the inner side of the beams B B to extend adistance downward therefrom, consisting of two spaced vertical beams 1and a transverse connecting beam, 2, the one support D being attached tothe wagoubeam B about the center thereof between the axles,while theother support, D, is attached to the opposite wagon-. beam B aboutone-half its length nearer the front axle,

rear braces, 3 and 4, which extend one across the other from thetransverse beams 2 of said supports to a connection with the wagonbeamsB and B opposite each support, as shown in Fig. 2. Each support D D isprovided with two metal guide-staples,-d d and d d, secured to the innerfaceof the transverse connecting-beams 2 thereof, the space between saidguides being regulated by the distance intervening between the diggerand scraper bars, hereinafter described. Two more metal guide-staples, bb and If D are secured to the wagon-beams B B between the vertical beams1 of the supports D D on the same plane with the above-mentioned lowerguide staples, d d and (Z d.

The digger-bar E, arranged at an angle across the wagon-frame, betweenthe wheels thereof, nearer the front than therear, is pro vided withvertical bars 6 0, one upon each side of the center, securely attachedthereto, which, passing through guards e eflprojecting from the top ofthe digger-bar E, extend upward, the vertical bar a through theguidestaple (Z of the support D and the staple b of the wagon-beam B,the opposite vertical bar, 0, through the staple d of the support D andthe staple btof the wagon-beam B. The object of the bars 0 and 6' thusheld is to guide v the digger-bar E when elevated at either end, orbodily from the ground, which operation is accomplished by means of theverticalhoistrods 5 and 6, connected at one end to the eyebolts 7,secured in the top of the digger-bar E upon each side of the verticalguide-bars e e, and at the other to long levers S,fulcru.med on shortstandrods 9, extending above the wagon-beams B and B, the said leversbeing provided with spring actuated pawls 10, adapted to engage theracked standards 11.

The said pawls are operated in conjunction with the long levers S,as thedigger-bar is ele vated thereby,through the pitman-rods 12 and shortlevers 13,pivoted to the handle ofthe long levers 8, as illustrated inFig. 1. The one lever, operating through the hoist-rod 5,is situatedupon the wagon-beam B, that operating hoist-rod 6 upon -wagon-beam B,their relative position upon the said wagon-beam being substantially thesame as the supports D D.

Teeth F, made long, pointed, and slender,are

adapted to be secured to the side of the digger-bar E, facing toward thefront wheels by means of short recessed plates f, bolted to the saiddigger-bar E over the teeth. As an ad ditional security, a screw isusually entered through the plates and teeth into the bar E. Behind eachtooth F, and bearing against the same a distance toward the end of saidteeth, is attached a supporti ng-block, f, purposed to impart additionalstrength to the slender teeth F and prevent the same from springing oryielding to the rear.

To overcome any side motion of the diggerhar E, Ifasten over the top ofthe wagonbeams B B, at an angle across the front axle, in a parallelline with the digger-bar, a stout brace-beam, G, to which the saiddiggerbar E is connected and held up to its work by brace-rods 1attached to the said digger-bar E and bracebeam G near their endsthrough eyeholts g g, as illustrated in Fig. 3.

Parallel with the digger-bar E, and at a moderate distance to the rearthereof, a scraperbar, H, is suspended and operated by means ofhoistrods 14. 15,attaehed to the upper edge thereof through eyebolts 16,which rods are attached to long levers 17, fulcru med in standards 18,provided with spring-actuated pawls 19, to operatein connect-ion withracked standards 20, together with pitmen 21 and attached short levers22. The device just described to operate the scraper-bar at either endor bodily, as desired, is a duplicate of the device heretofore mentionedas employed in vertically adjusting the digger-bar E, the standards 18and 20 being secured to the beams 13 and B to the rear of the standards1 and 9 upon the wagon-beam.

The scraper-bar is provided with upwardlyextending guide-rods h 7!,similar to and parallel with the guiderods c c of the digger-bar, which,passing through guards 7i hflprojecting from the top of saidscraper-bar, extend upward. the vertical bar It through the lower andupper aligned staples, (Z and b, respectively situated upon thetransverse bar 2 of the support D, and the wagon-beam B and the verticalbar It through the opposite lower and upper al igned guide-staples, dand If, respectively situated upon the transverse bar 2 of the sup portD, and the wagon-beam B performing the same function for the scraper-barH as the aforesaid vertical bars 0 and e do for the diggcr-barE.

The scraper-bar H is provided with a blade, H, having its eutting-edgcconcaved the length of said blade, the concavity thereof conforming tothe standard convexity of ordinary roads, and the end which is parallelwith the end of the digger-bar E, adapted to take the gutter side of theroad, is formed with a sharp cutting-edge, K, to enter the groundreadily and form the road at this point. The extended portion of theblade, which extends nearly to or over the crown of the road, isprovided with a taper, K, to save metal and weight,as heavy work is notrequi red at this point. The scraperbar H. is held securelyin positionby means of brace-rods M, which are fastened at one end to theseraper-bar H and at the other to a bracebcam, M, said. beam. beingplaced at an angle over the top of the wagon-beams B B, to the rear ofthe digger brace-beam G, parallel therewith and with the scraper-bar.The bracerods M, thus connected with the scraper bar, prevent any sidemotion of the same.

The use of a concave bar on a road saves much time in working, coveringnearly twice the space attainable by a straight blade, and at times theuse of the digger may be dispensed with, as the concavity of the bladeand its sharp end enables the scraper to form anew the road-surface, ifnot badly torn. Again, the concave blade will carry the refuse from thecenter of the road to the ditch,which cannot be done with a straightblade. \Vith the light tapering point the blade can be extended to covera large portion of the road at once.

As will be seen from the drawings and description, the digger-bar andthe scrapeubar are controlled byindependent levers at each end, or canbe elevated equally their length. This greatly facilitates workingdownhill or on roads where a great convexity or crown is employed.

The draft is applied directly to the kingbolt, and, when the wagon isconstructed, as shown, with short axles in front, is brought near thehorses, and as the draft is entirely from the forward end the rearwheels remain at all times upon the ground,preventing the wagonfronrmoving sidewise out of the line of draft, which would not be thecase were the draft partly from the rear. Vhen de sired, ordinarysod-cutters may be substituted, partly or entirely, for the diggertceth.

In the operation of my combined digger and grader, the diggers orsod-cutters, after being adj usted by means of their lovers to thenature of the road, as the team advances turn the same up, and as thebar is ordinarily elevated at the side nearest the crown the diggerswill work deepest near the ditch, and gradually cease digging near thecenter. The scraper, fol lowing immediately behind,with its concavededgeblade and sharp point quickly and handsomely forms the contour of theroad in a short space of time. Any ordinary wagonframe may be usedinstead of the form shown. The latter is, however, preferable.

The digger-bar and teeth may be used independent] y of the scraper. Forinstance, in working downhill the pulverizing can be done upon bothsides of the road by the digger, and then covered by the scraper.

Vhen the ground is very hard it is permissible in my construction ofdiggerbar to use the end teeth only in starting a break. This isaccomplished by simply elevating the bar to its greatest height upon oneside. The remainder of the work is thus made easier for either bar, andthe labor divided according to the strength of the team employed.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. In a road digger and scraper, the combination, with a wagon-framehaving ascraperbar suspended therefrom, substantially as described, of ascraper-blade having its edge concaved the length thereof, provided withan angular point at one end and a gradual taper at the other,substantially as herein set forth, and for the purposes described.
